Andreev conductance of a domain wall [PDF]
, 2003 At low temperatures, the transport through a superconductor-ferromagnet tunnel interface is due to tunneling of electrons in pairs. Exchange field of a monodomain ferromagnet aligns electron spins and suppresses the two electron tunneling.

Optimisation of a three-terminal nonlinear heat nano-engine
New Journal of Physics, 2016 Charge and heat transport in nano-structures is dominated by non-equilibrium effects which strongly influence their behaviour. These effects are studied in a setup consisting of three external leads, one of which is considered as a heat reservoir and is ...

Currents and fluctuations of quantum heat transport in harmonic chains
New Journal of Physics, 2017 Heat transport in open quantum systems is particularly susceptible to the modeling of system–reservoir interactions. It thus requires us to consistently treat the coupling between a quantum system and its environment.

Quantum and Classical Binomial Distributions for the Charge Transmitted through Coherent Conductor [PDF]
, 2003 We discuss controversial results for the statistics of charge transport through coherent conductors. Two distribution functions for the charge transmitted was obtained previously, first by L.Levitov and G.Lesovik, [JETP Letters Vol.55 p.555 (1992)] and ...

Long-Range Electron Transfer and Electronic Transport Through Macromolecules
, 2005 A theory of electrical transport through molecular wires is used to estimate the electronic factor in the intramolecular electron transfer (ET) in porphyrin-nitrobenzene supermolecules, and to analyze its structure.

Invariance of the Kohn (sloshing) mode in a conserving theory [PDF]
, 2007 It is proven that the center of mass (COM or Kohn) oscillation of a many-body system in a harmonic trap coincides with the motion of a single particle as long as conserving approximations are applied to treat the interactions.

, 2008 In time reversal symmetric systems with half integral spins (or more concretely, systems with an antiunitary symmetry that squares to -1 and commutes with the Hamiltonian) the transmission eigenvalues of the scattering matrix come in pairs.

Optical response of electrons in a random potential
, 2004 Using our recently developed Chebyshev expansion technique for finite-temperature dynamical correlation functions we numerically study the AC conductivity $\sigma(\omega)$ of the Anderson model on large cubic clusters of up to $100^3$ sites.

Convergence of macrostates under reproducible processes
, 2010 I show that whenever a system undergoes a reproducible macroscopic process the mutual distinguishability of macrostates, as measured by their relative entropy, diminishes.
